Underwire bras are the most popular bras in the field and offer great support, lift and shaping. Although older styles had an actual wire sewn between fabric layers under the bra cups, today, underwires may be made of flexible plastic or plastic coated metal. Because of their popularity, underwire bras come in virtually any style and fabric. Innovations in bra construction have led to the utilization of microfiber and there are many microfiber underwire bra styles to choose from.
Microfiber, which is a tightly knit synthetic fabric made from extremely fine filaments, is ultra smooth and soft. It is a breathable light fabric that is also very durable. Because microfiber can be shaped and molded for any bra style, it's become almost ubiquitous in the lingerie industry. A well-constructed underwire microfiber bra will be ideal under clingy materials, knits and tees--giving you a smooth and shapely silhouette.
